Fuse Energy Secures $70 Million in Series B Funding to Fuel Global Growth

Fuse Energy, a fast-growing energy infrastructure startup, has raised $70 million in Series B funding, led by Balderton Capital and Lowercarbon Capital, bringing its valuation to approximately $5 billion just three years after its founding.

The London-based company — co-founded by ex-Revolut executives Alan Chang and Charles Orr — is focused on vertical integration across the energy value chain, from renewable site construction and power generation to trading, supply, installations, and energy hardware. This integrated model aims to drive down costs and inefficiencies compared to traditional energy suppliers.

Unlike many competitors that outsource generation and trading, Fuse combines these functions under one roof to deliver lower-cost, reliable renewable energy and energy products to households and businesses. This strategy has helped the company serve over 200,000 customers in the UK and drive strong revenue growth while making clean energy more affordable.

What the funding will support:

International Expansion: Plans include scaling operations into key markets such as Ireland, Spain, and the United States, leveraging the new capital to build infrastructure and local teams.

Product Innovation: Part of the funds will accelerate the development and launch of hardware solutions (e.g., affordable micro solar-battery kits) and grid-balancing innovations like The Energy Network, which is designed to reward off-peak energy usage.

Grid & Customer Growth: With global demand rising for electrification, renewables, and energy cost control, Fuse aims to extend its vertically integrated platform to deliver lower prices and enhanced reliability.

Why it matters: Fuse’s rapid rise — including its $5 billion valuation — highlights investor confidence in integrated clean energy solutions that address inefficiencies in traditional power markets and support the transition to renewables on a large scale.
